could be just a skin rash type thing. during pregnancy and after, our hormones kinda go a bit crazy from time to time and sometimes that can lead so some kind of skin reactions in terms of rashes or allergies. My 1st pregnancy I started developing small reddish patches here and there that itched. Doc gave me a cream for them but didn't really help. They went away after a while though. Now my 2nd pregnancy also the same. The same reddish patches starting to show up again. Maybe you can just go see a doc if it bothers you or more turns up. But otherwise, I think it should be alright.
